Field of the Invention
[0001] The present invention relates to a device and method for the treatment of adhesive
capsulitis. The invention has been developed primarily for use in respect of the treatment
of adhesive capsulitis and will be described hereinafter with reference to this application.
However, it will be appreciated that the invention is not limited to this application
or particular field of use.
Background
[0002] Adhesive capsulitis, or frozen shoulder as it is commonly known, is a disorder in
which the shoulder capsule and the connective tissue becomes inflamed and stiff causing
chronic pain.
[0003] Existing means of treatment may employ anti-inflammatory drugs or the application
of heat. In some cases electrical nerve stimulation may be used to reduce pain by
blocking nerve impulses. In extreme cases, manipulation of the shoulder under general
anesthesia is required to break up the adhesions.
[0004] An example of an existing means of treatment is shown in
US 2010/0076354 A1 which discloses a shoulder continuous passive motion (CPM) device. The CPM device
has a motor and a drive mechanism that is configured to move a slidable arm holder
linearly back and forth. A user can insert at least a portion of his arm into the
arm holder such that the CPM device moves his arm linearly back and forth.
[0005] However, existing arrangements suffer from numerous disadvantages, including being
ineffective, painful and requiring the presence of medical staff.
[0006] As such, a need therefore exists for a device and method for the treatment of adhesive
capsulitis that is effective, less painful and may be performed without the supervision
of medical staff. It is to be understood that, if any prior art information is referred
to herein, such reference does not constitute an admission that the information forms
part of the common general knowledge in the art, in Australia or any other country.

capsulitis which will overcome or substantially ameliorate at least some of the deficiencies
of the prior art, or to at least provide an alternative.

profile that may be varied according to certain parameters, such as the physical characteristics
of the patient, progress of treatment and the like. Further advantageously, the mechanical
coupling between the manipulation effector and driven oscillator can be chosen according
to the operational requirements of the device, such as the weight, power consumption

[0013] Advantageously, the amplitude and frequency of the point-to-point motion profile
are chosen so as to most effectively treat the joint.
[0014] Advantageously, a relatively simple mechanical arrangement may be employed to displace
the manipulation effector in accordance with the point-to-point profile.
[0015] Preferably, the manipulation effector is adapted to move in a point-to-point motion
profile comprising at least one phase of motion comprising a jerk motion.
[0016] Advantageously, the jerk motion further enhances the effectiveness of the treatment.
[0017] Preferably, the manipulation effector is adapted to move in a point-to-point motion
profile comprising:
a first phase of motion under increasing acceleration;
a second phase of motion under constant acceleration;

Detailed Description of Specific Embodiments
[0028] It should be noted in the following description that like or the same reference numerals
in different embodiments denote the same or similar features.
[0029] Figs. 1a and 1b shows a block diagram of the functional components of a device 100
for the treatment of adhesive capsulitis in a joint of a patient. In other embodiments,
the device 100 may be suited to the treatment of other disorders, such as disorders
similar to adhesive capsulitis, including calcific tendinitis and the like. The device
100 comprises a driven oscillator 105 coupled to a manipulation effector 115 by a
coupling 110.
[0030] The manipulation effector 115 is adapted to manipulate the joint so as to treat the
adhesive capsulitis of the joint. The manipulation effector 115 typically manipulates
the limb of the patient comprising the joint, but may also, in other embodiments,
manipulate the joint directly, by applying force directly to the joint. As such, the
manipulation effector 115 may be adapted to attach to the limb of the patient, for
example by way of a releasable cuff secured in place by hook and loop fasteners. In
other embodiments, the manipulation effector 115 is adapted to be grasped by a hand
of the patient. In further embodiments the manipulation effector 115 does not attach
to the limb of the patient, but merely bears upon the limb so as to apply force to
the limb.
[0031] The driven oscillator 105 is adapted to displace the manipulation effector 115 in
accordance with a point-to-point motion profile. The point-to-point motion profile
may be chosen to maximise the treatment of the adhesive capsulitis. Various mechanical
arrangements, some of which are described herein, may be employed to couple the driven
oscillator 105 to the manipulation effector 115 to displace the manipulation effector
115 in accordance with a particular point-to-point motion profile.
[0032] Fig. 2a shows a first exemplary point-to-point motion profile 200a. The point-to-point
motion profile 200a may be realized using a relatively simple mechanical arrangement.
Specifically, as shown in the acceleration plot, the point-to-point motion profile
200a comprises a first phase of motion under constant acceleration, a second phase
of motion under zero acceleration and a third phase of motion under constant deceleration.
As is shown in the velocity plot of the point-to-point motion profile 200a, the manipulation
effector 115, starting from rest, linearly increases in velocity during the first
phase. During the second phase, the manipulation effector 115 experiences zero acceleration
and travels at constant velocity. During the third and final phase, the manipulation
effector 115 experiences deceleration and the velocity of the manipulation effector
115 decreases in a linear fashion until the manipulation effector 115 comes to rest.
[0033] Fig. 2b shows a second exemplary point-to-point motion profile 200b. The point-to-point
motion profile 200b comprises at least one phase of motion comprising a jerk motion.
The jerk motion further increases the effectiveness of the treatment of adhesive capsulitis.
In the embodiment shown in Fig. 2b, the point-to-point motion profile 200b comprises
one or more phases of motion, comprising a first phase of motion under increasing
acceleration, a second phase of motion under constant acceleration, a third phase
of motion under decreasing acceleration, a fourth phase of motion under zero acceleration,
a fifth phase of motion under increasing deceleration, a sixth phase of motion under
constant deceleration and a seventh phase of motion under decreasing deceleration.
[0034] In one embodiment, the point-to-point motion profile comprises between 200-4,000
strokes per minute and preferably, between 400-3,500 strokes per minute
[0035] In one embodiment, the point-to-point motion profile has a displacement of between
3mm and 12mm. In a more specific embodiment, the point-to-point motion profile has
a displacement of between 5mm and 10mm. In an even further specific embodiment, the
point-to-point motion profile has a displacement of about 7.5mm. Furthermore, in one
embodiment, the point-to-point motion profile has a period of between 0.015s and 0.3s.
In a more specific embodiment, the point-to-point motion profile has a period of between
0.016s and 0.9s. In an even further specific embodiment, the point-to-point motion
profile has a period of between 0.017s and 0.15s.
[0036] In use, in one embodiment, the patient may be positioned in a treatment position,
such as a sitting position or a prone position. The limb of the patient comprising
the affected joint may be allowed to hang vertically downwards. The device 100 is
then attached to the limb and set in an operational mode. In this manner, the inertia
generated by the driven oscillator 105 displace the manipulation effector 115 so as
to manipulate the limb.
[0037] In an alternative embodiment, the device further comprises an anchor 120 distal to
the manipulation effector and adapted for securement to an immovable object, such
as a door knob or bolt secured within a wall. In this manner, the device 100, secured
by the anchor 120, exerts a resultant force upon the manipulation effector 115.
[0038] While the embodiment shown in Figs. 1a and 1b shows the anchor 120, driven oscillator
105 and manipulation effector 115 as being integral, it should be noted that, in various
other embodiments, the anchor 120, driven oscillator 105 and manipulation effector
115 may be coupled in various configurations, or located in various places. It should
be noted also that the driven oscillator 105 may exert direct force on either the
anchor 120 or the manipulation effector 115, such that a resultant force is generated
to displace either the manipulation effector 115 or the body of the device 100.
[0039] For example, the driven oscillator 105 and anchor 120 may be located away from the
manipulation effector 115, perhaps by the driven oscillator 105 being located at and
attached to an immovable object by the anchor 120, and connected to the manipulation
effector 115, such as a wrist cuff, by a coupling 110, such as a cord. In this manner
the driven oscillator 105, located at the immovable object, exerts force on the cord,
causing the manipulation effector 115 to maniplulate the joint.
[0040] In another example, the driven oscillator 105 and manipulation effector 115 may be
integral, with the anchor 120 being attached to an immovable object and the driven
oscillator 105 being attached to the anchor 120 by a cord so as to impart a resultant
force upon the manipulation effector 115.
[0041] In certain embodiments, the manipulation effector 115 is adapted for grasping by
a hand of the patient. For example, the manipulation effector 115 may be shaped as
a handle, allowing the patient to grasp the manipulation effector 115 during treatment.
Alternatively, the manipulation effector 115 may comprise releasable attachment means
adapted for attachment to a limb of the patient. For example, the manipulation effector
115 may comprise a cuff adapted to be secured about the limb of the patient, perhaps
at the wrist. The cuff may be secured by complimentary hook and loop fastening means.
[0042] Fig 1a shows a preferred embodiment in which the device 100 comprises a motor 140
coupled to a power supply 135 and adapted to drive the driven oscillator 105. In a
further specific embodiment not covered by the invention, Fig. 3 shows the device
100 comprising a drive shaft 120 coupling the motor 145 and the driven oscillator
125. In one particular embodiment, the driven oscillator 105 is mechanically coupled
to the drive shaft 120 by a crank 305 adapted to impart a linear reciprocating motion
325 upon the driven oscillator 105 when the motor is in use. Specifically, the drive
shaft 140 comprises a bearing surface 310 having an axis 315 offset from the axis
320 of the drive shaft and wherein the crank 305 bears against the bearing surface.
[0043] Alternatively, in an embodiment covered by the invention, the driven oscillator 105
is mechanically coupled to the drive shaft 140 at an attachment point offset from
the axis of the drive shaft 140 and adapted to impart a rotational motion upon the
driven oscillator 105 when the motor is in use.
[0044] In one embodiment, the drive shaft 140 may be a lengthy flexible drive shaft 140
encased in a protective sheath. Such an arrangement would allow the motor to be located
some distance from the driven oscillator 105, perhaps on the floor of the treatment
room.
[0045] In this manner, the motor 125 may be an electric motor, perhaps a direct current
motor coupled to a direct current power supply, such as a rechargeable battery pack.
Alternatively, the motor 125 may be an alternating current motor coupled to an alternating
current power supply, such as an electric wall socket.
[0046] In an alternative embodiment not covered by the invention, as shown in Fig. 1b, the
device 100 further comprises an electromagnet 130 magnetically coupled to the driven
oscillator and adapted to impart a linearly reciprocating motion upon the driven oscillator
105 in use. For example, the driven oscillator 105 may be comprised of metal and magnetically
coupled to the electromagnet 130. As such, the periodic energisation of the electromagnet
130 may attract or repel the driven oscillator 105, thereby imparting a reciprocating
motion upon the driven oscillator 105. In certain embodiments, the device 100 may
be provided with both the electromagnet 130 and the motor 140.
[0047] Fig. 4 shows a method 400 of treatment for adhesive capsulitis in a joint of a limb
of a patient. The method comprising at least the step 405 of manipulating the limb
of the patient in accordance with the point-to-point motion profile 200.
[0048] In one embodiment, the step 405 of manipulating the limb of the patient comprises
step placing the limb of the patient under longitudinal compression or longitudinal
tension to as to further increase the efficiency of the treatment. The patient may
be placed in a supine position and the limb manipulated patient in a vertical direction.
Alternatively, the patient may be placed in a prone position and the limb manipulated
in a vertical direction. Yet further, the patient may be placed in a seated position
and the limb manipulated in a horizontal or vertical direction.
[0049] Typically, the step of manipulating 405 the limb of the patient in accordance with
a point-to-point motion profile is repeated between 1 and 5 times but preferably the
step of manipulating the limb of the patient in accordance with a point-to-point motion
profile is repeated 3 times. Furthermore, the step 405 of manipulating the limb of
the patient comprises the step of manipulating the limb of the patient for a duration
of between 0.5 and 10 minutes.
[0050] In certain embodiments, the method 400 comprises steps 410 to 420 to treat the adhesion
of the muscle tissue surrounding the joint. Specifically, the method 400 comprises
step 410 where gentle pressure is applied to the tissue surrounding the joint. At
step 415, one or more areas of sensitivity are identified. At step 420 the one or
more areas of sensitivity are massaged, typically for between 5 and 40 minutes and
preferably for between 15 and 25 minutes, until the sensitivity decreases. Any of
steps 410 to 420 may be repeated any number of times.
[0051] While step 420 may be performed manually, the device 100 having a driven oscillator
105 and a manipulation effector 115 mechanically coupled to the driven oscillator
105, may be provided to displace the limb in accordance with the point-to-point motion
profile. In this manner, the manipulation effector 115 may be attached to the limb
of the patient; and the device 100 operated to manipulate the limb.
[0052] Turning now to Figs. 5 to 14, there is shown an embodiment of the device 100 as an
hand-held appliance. In this embodiment, the device 100 is provided with a ruggedized
and portable construction so as to be suitable for use in the home, in a physiotherapy
practice and the like. Typically, the device 100 will weigh no more than 5kg and comprise
a durable plastic outer shell. The device 100 may be battery operated, such as by
a lightweight Lithium-ion battery, or powered as is shown in figures, either by AC
or DC power.
[0053] Fig. 5 shows a top view of the device 100 with the manipulation effector 115 extending
therefrom. Herein, the manipulation effector 115 comprises an attachment point, such
as a hole 520 in the embodiment shown, for the purposes of attachment of a strap,
handle or the like for attachment to a limb of a patient. In this manner, the device
100 may be held by a treatment provider in manipulating the limb of the patient. Also,
as will be described in further detail below, the device 100 may further comprise
an anchor 120 located distally from the manipulation effector 115 for the purposes
of anchoring the device 100 such that no manual handing of the device is required
by the treatment provider in use. The anchor 120 further allows the device 100 to
be attached to various convenient attachments points, such as a door knob in a house.
[0054] The device 100 comprises a flexible power cord 505 and a control cord 510 for a controller
as described in further detail below. The device 100 further comprises a handle 515,
for carrying the device.
[0055] Fig. 6 shows a side view of the device 100 in this embodiment.
[0056] Fig. 7 shows a side view of the device 100 in use, wherein the device 100 is coupled
to a patient engagement 705 and an anchor point 710. As alluded to above, the patient
engagement 705 may be any suitable means for attachment to the patient but typically
attaches to the wrist of the patient (therefore taking on the form of a releasable
strap) or is held by the hand of the patient (therefore taking on the form of a handle).
Also, the anchor point 710 may be any suitable anchor point, typically located in
various orientations, such as at shoulder height to effect laterally on the shoulder
joint of the patient or above head height to effect vertically on the shoulder joint
of the patient. One or more hooks 720, 715 may be used as the case may be for releasable
engagement to the device 100.
[0057] Fig. 8 shows a bottom view of the device 100 having a substantially planar bottom
surface, being suitable for resting on flat surfaces.
[0058] Fig. 9 shows a top view of the device 100 in this embodiment.
[0059] Turning now, to Fig. 10, there is shown an internal view of the device 100. The device
100 comprises a control PCB 1025. The control PCB 1025 may comprise relay switching
for being suitable for 100-240v AC. The control PCB 1025 is wired to the controller
(described below) or may be wireless coupled to the controller where the controller
is a wireless controller.
[0060] The device 100 further comprises an electric motor 1005 coupled to a cooling fan
1010 and rotary drive coupling 1015.
[0061] The device 100 further comprises geared transmission 1020 coupled between the rotary
drive coupling 1015 and the manipulation effector 115 employing a piston and shaft
drive so as to impart rotary motion from the rotary drive coupling 1015 into reciprocating
point-to-point motion.
[0062] Turning now to Fig. 11, there is shown a controller 1100 for remote control of the
device 100. The controller 1100 may be wired to the device using control cord 510
or may be wirelessly coupled to the device 100, by radio wave, infrared and the like.
[0063] Fig. 12 shows a perspective view of the controller 1100 wherein the controller 1100
comprises a display device 1230 indicating a cycle operating time, usually in the
form of a numerical countdown. The controller 1100 further comprises time control
buttons having a time control button 1235 for increasing the cycle time and a time
control button 1240 for decreasing the cycle time.
[0064] Similarly, the controller 1100 further comprises frequency control buttons having
a frequency control button 1220 for increasing the stroke speed of the manipulation
effector and a frequency control button 1240 for decreasing the stroke speed. The
controller 1100 further comprises a display device 1215 for displaying the current
stroke speed.
[0065] Note that in certain embodiments the controller 1100 may comprise control buttons
for controlling the stroke distance of the manipulation effector.
[0066] The controller 1100 further comprises a start/stop button 1205 for activating and
deactivating the device 100.
[0067] By default, the controller 1100 is adapted to use the last setting upon powerup.
